Ruger Mk. II Assembly PROBLEMS!

[Burke888]

I can get the gun back together fine, its just when it is back together the following happens;

1. The slide seems pretty hard to pull back, like it has extra tension.

2. When I pull back the slide, the trigger isn't cocked.

3. The saftey will not go from "Fire" to "Safe"

What could be the problem?

(I was never able to disasemble the pistol at all. I got to the point when the main spring housing swings open, but I was never able to pull it out completly out of the gun)

The link above may help. I had some problems with re-assembling my 22/45 and I was directed here by another member.

Hope this helps.

Sounds like the hammer strut isn't in the right spot. Pull the mainspring housing down, point the gun up, and pull the trigger. The strut should be hanging out of the slot where MSH belongs. Keep the gun tilted back while you push the MSH back into place.

Give that a shot.

I had trouble with my MKIII 22/45, make sure you read the directions and follow each step carefully. I tried to beat mine with a rubber mallet until I read more carefully and things came apart and went together smoothly. Good Luck TJ

When is Ruger gonna paint the hammer strut red and paint something inappropriate around the open end of the mainspring housing?

Don't worry, this happens to everyone a couple of times. PITA until you get used to it.

Also, a cable tie with a small loop at the end makes a good no-mar tool for pulling open the mainspring thingy. Mines all scratched up from using screwdrivers, nail files, pipewrenches and the like. Don't let this happen to you. ;f

are the mark 3s easier to reassemble?THE MARK 2 WERE A NIGHT MARE.PERIOD TO REASSEMBLE.

I have never taken my mark II apart. I clean the barrel with a rod and spray some gun scrubber in there to get the loose powder out, oil it up and been using it for years and years and years like this.

I should add that it just works and works and works and works and works. Love the gun.

You might shine a flashlight up the magazine housing and see if there is much gunk up there. It builds up pretty well around the trigger mechanism.

Here in the innards of my gun, fairly clean but there's still a bit of gunk in there

Myself and a good friend of mine have determined over the last 15 years or so that all Mark II's function best if they have not been cleaned in the last 500 rounds or so. I recommend cleaning it as little as possible (maybe every 4-5K rounds).

You mean they come apart?????;b

there is no reason to strip down a mark 2.their impossable to put together on a consitant basis.i used to spray mine out with rem oil after the first time i had to carry it to a gun smith for reassembly.i since sold them off.i dont need a pistol that difficult to reassemble!

I can fieldstrip mine and re-assemble it in less than 30 seconds. There's nothing to it once you learn a couple of little tricks.

Make sure the hammer is lieing flat when you put the upper on and the hammer strut is visible from the rear of the gun.

After you push the pin on the top of the mainspring housing into the bolt hold the trigger back while pointing the gun downward. If you don't do this the pin will come out of the bolt.

Once you do that point the gun upward at the right angle (the only tricky thing to learn) as you close the mainspring housing the last little bit. You know you have it right if you feel spring tension in that last 1/4 inch or so as you push the mainspring housing in. There is a dimple in the mainspring housing. The is where the hammer strut goes and under this dimple is the hammer spring.

You can assemble the mainspring housing with the barrel/bolt missing so you can see exactly how it works.

That's it. I don't know why people have so much trouble with these.

+1 took mine to the local shop in shoebox the first time I took mine 1st gen markII apart. Darwin, you nailed it!

A few years back at one of the ranges I go to, a guy was in there with the shoebox and a puzzled look on his face (had the MKII of course). Even the guy behind the counter looked puzzled as he tried to help.

When my ex-wife came home with HER new 22/45 I had to take a stab at it, and somehow managed to nail it right off the bat, and did it maybe 4-5 times without any issues. Then on attempt #6 or so I had the good ole' "it is together but not functioning".. Took about 30 minutes to figure out why all of a sudden it wasn't going together right.

Those pistols are actually easy to get back together by follwing the directions in the manual exactly, but the problem is that they don't explain WHY in enough detail (ie..the part about having it a certain angle when you get the mainspring housing back in place).

I think someone already mentioned, but the trick to knowing if it's going back together right is the 1/4-1/16" or so that the housing stops before it fits flush. If it just pops in and goes flush then it's NOT lined up correctly. And if you've gotten it back together wrong, and try to do a function check it's a bear to get back apart to get it *back* together right. Don't ask how I know THAT! hee hee.

Come to think of it, Ruger should almost include a video with each MKII showing how to re-assemble. :cool:
